Patented May 23, 1939 UNlTEDaS'TA-TES PATENT OFFICE Application June 16, 1937, Serial No. 148,538 Renewed March 27, 1939 3 Claims.

This invention relates to devices that may be used for controlling the winding of material, such as window-shades.

One of the objects of this invention is to provide a means to act against the tendency of material to run endwise one way or another upon any winding. I

Another object is to provide means that may be applied to a window in such a manner that a window-shade will wind straight without any particular great attention.

Other objects will appear from the following description and appended claims as Well as from the accompanying drawing, in which-- Fig. 1 is a fragmentary front elevation of a window-sash and a shade in co-relative positions as commonly used, having a guide indicated over the center between the sash and shade.

Fig. 2 is an end view of the illustration of Fig. 1.

Fig. 3 is a fragmentary cross section on line .33 of Fig. 2, slightly enlarged, the section being shown as through the guide members as well as through a part of the sash and also through the shade-bar.

Fig. 4 is a cross section of a slightly modified form.

Fig. 5 is a cross section through a slightly modified form of guide bar.

Fig. 6 is a cross section through another slightly modified form of guide bar.

Fig. '7 is a perspective view of a slide to ride on a guide bar.

Window shades are commonly wound upon spring-actuated rollers, and it takes a certain amount of attention to get the shade to wind up evenly.

A shade has the tendency to run edgewise one I way or another to such an extent that it will not only wedge against the supports but in time wear off unduly or undesirably quickly.

Such edgewise running makes a shade soon appear untidy or ragged.

It is also irritating to see a shade run edgewise, and it requires a certain amount of time and patience, that often is not applied, particularly, perhaps by renters, to the undesired expense of the owner of the place.

The very slightest of guiding would be sumcient to assure a proper Winding, and rather thin and light material can be used for such guiding means.

Some windows are provided with central members such as indicated at 8 in Fig. 1, in which case a guiding is best accomplished by a central application.

However, inasmuch as it on takes so little to guide a shade, a guiding meat may be applied at either end of the shade, or, of course, also at both ends.

A guide bar 9 is indicated in Figs. 1 and 2 for the slide [0, the bar being applied to the sash ll, while the slide is applied to the shade l 2.

Since generally some sort of handle, as a string, is applied to the lower end of the shade, this central application of the guiding means is, of course the most practical.

The most desirable form is, perhaps, the one illustrated in Fig. 3, the guide-bar 9a being secured to the member 83.; while a slide Illa is secured to the lower edge piece I3 oi the shade.

This particular form of guide-bar 9a is provided with a channel-portion, deep enough that the heads l4 and I5 of the securing means may pass freely while the guiding means is being used and operated. 20

Providing the outermost edges I6 of the guidebar of such a form that the rolled-in edges ll of the slide "is can easily ride along the guide-bar in such a manner that the attached shade will be properly guided with respect to a window, eliminates any edgewise running of the shade though the customary string or other handle means is used extremely carelessly and not at all squarely to the shade or winding roller.

Fig. 4 shows a slightly modified form of guiding means, the member 83. being grooved as indicated at l8, a plate [9, slotted along the center as indicated at 20, being secured to the member 8a, and a button-like member 2| being secured to the edge member l3 of the shade to ride in the slot of the plate l9.

Fig. 5 shows another slightly modified form for the guide-bar as indicated at 22, to be rather narrow and solid, of almost any sort of material, metal, or wood, through which the securing means can be driven right through.

Fig. 6 shows still another slightly modified form for the guide-bar indicated at 23, a rail-like shape that allows securing means to be driven in sidewise of and past the front guiding edge of the rail.

A slide is illustrated in detail in Fig. '7 of a form to readily slide on and over the guide-bar 9, the lugs 24 being the terminations of the rolledin edges ll, referred to with reference to the illustration in Fig. 3, and the hole 25 being provided for pivotally engaging the pin by which the slide is attached to the edge piece 13 of the shade I2.

Using a pivot connection at this point provides a means by which a shade may be jerked up quickly without any wedging or binding of the slide on the guide-bar, particularly, when only one guiding means is provided at one of the ends of the edge piece l3, the slide simply following as best it can on the guide bar regardless of any quicker movement momentarily, as in jerks, of the shade at other places away from the guiding point.

Having thus described my invention, I claim:

1. In a guide for window shades, a slide member provided with doubled-up edge-portions forming guiding engaging means for the slide and provided with a pivot means whereby any attached shade may move freely against wedging tendencies.

2. In a guide for window shades, a guide bar made of sheet material evenly depressed centrally with raised edges, and a slide member provided with means to engage over said raised edges of the bar and having means to pivotally engage with the shade of a window for maintaining the shade in a desired path while being wound and unwound.

3. In a guide for window shades, a guide bar having guiding means along the opposite edges, and a slide member provided with means to engage over said edges for sliding engagement with the guide bar and having means to pivotally engage with the shade of a window for maintaining the shade in a desired path while being wound and unwound.
